.AIR-BRUSH.

Specicatonof Letters Patent.

Patented May 30, 1916.

Application led April 29, 1915. Serial N o. 24,697.

To all whom t may confiera Be it known that I, JOSEPH E. PHILIBERT, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, heve invented certain new an-d useful Improvements in Air-Brushes, of which the following is a specification.

This invention relates to new and useful improvements in air brushes.

The object of the invention resides in the provision of a device of the character described, whereby one or a plurality of fluids may be sprayed from a single device under the influence of a single air jet; and while the brush may be used for spraying any kind of fluid, it is primarily intended for spraying paints, or colors, where it is desired to frequently change the color employed or to spray a combination of colors at the same time.

A further feature of the invention resides in the prov-ision of means whereby the discharge nozzle may be restricted, so as to control the amount of spray discharged.

`With the above and other objects in view,

y the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1, is a side elevation of thedevice. Fig. 2, is an end view thereof. Fig. 3, is a plan view thereof. Fig. 4, is a vertical sec- `tional view thereof, and Figs. 5 to 8, inclusive, are detail sectional views of the operative parts employed.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1, refers to an oblong cylindrical casing, having a tapering or restricted discharge 2, to which a needle valve casing is attached, set in oblique relation and converging toward the discharge at the forward ends. Extending axially through this casing is the needle valve 4, whose forward end is tapered and projects into the discharge 2 and is provided to control the flow of fluid through the discharge. The other end of the needle valve has a bearing in the member 5, which is attached to and upstands from the nozzle. A smalll thumbshaft 6, has a bearing in said member and contacts with the needle valve and tlpir contacting parts are milled or geared, as lllustrated in Fig. 8, so that by turning the thumb-shaft, `the tapered end of the needle valve -may be projected into, or withdrawn from, the discharge passage way and the same opened, restricted, or closed, as desired. lhe nozzle has an air passage way 7, extending axially entirely therethrough, whose end, opposite the discharge, communicates with an inlet pipe 8, which in turn, communicates with an air compressor (not shown), through a suitable hose, as 9, and from which a jet of air may be driven through said nozzle and discharged. rlhe inlet pipe 8, is controlled by a gate valve, 10, which is slidably mounted in the casing 11, carried by said pipe, and whichhas an aperture 12, therethrough `near one end. This valve is' seated, on a resilient cushion V13, within the casing, and normally blocks the pipe 8 and completely cuts ofl the air current. A rod 14, is attached to the valve 10 and projects out through the casing and by pressing the same, the aperture may be ,f

brought into alinement with the pipe 8, and the stream of air permitted to pass therethrough and into the nozzle.

A casing 15, is provided which'is xed with respect to the nozzle and inlet pipe through the medium of the bracket 16, attached to the bottom of the casing and surrounding and fixed to the inlet pipe and formed into a grip or handle 17. A plurality of fluid containers 18, are arranged, side by side, and fixed in the casing 15, and fixed to the nozzle and communicating with the air passage way 7, thereof, are the tubes 19, which extend down into the respective containers approximately to the bottoms thereof, The containers are filled with paints or colors of different tints, which are sprayed through lthe discharge either separately or in combination in the manner hereinafter described. The upper end of each tube 19, is controlled by a gate-valve, as 20, having a transverse slot 21, therethrough, which at all times, registers with j the air passage way 7 These valves 20, are

slidably mounted between the transversev .vice can be used to valve 20, normally blocks the upper end of the corresponding tube 19, but when pres# sure is exerted on the push-rod 24, and the cushion 23, depressed, the aperture 25, is brought into registration with the corresponding tube 19. This aperture extends through the under side of the valve 20, and permits the tube 19 to communicate With the air passage Way 7.

In operation, the lvalve 10, is first opened, permitting the air to be forced through the passage Way -7, of the nozzle. When either of the valves 20 is then` opened, the fluid in the corresponding container 18, Will be drawn therefrom through its tube 19, by suction and sprayed through the discharge 4, on to the intended surface.l If a combination of colors is desired, it is obvious that by opening the valves `20, controlling the different containers containing the desired colors, the combination sought, will be obtained. It is obvious further that the despray a single color, different colors, successively, and a combination of colors, at the same time.

What I claim is:

1. A device of the character described including a nozzle having an air passage Way therethrough with a restricted discharge, an air inlet to said passage Way, a means for blocking and unblocking said inlet and a plurality of containers communicating separately with said passage Way.

2. A device of the character described including a nozzle having an air passage Way therethrough with a restricted discharge, a needle valve provided to restrict said discharge, an air inlet to said passage Way, a means for blocking and unblocking said inlet,and a plurality of containers communicating separately with said passage Way.

3. A device of the character described including a nozzle having an air passage Way therethrough with a restricted discharge, an

.ality of containers fixed Liemeer inlet to said passage' way, a ymeans for blockililg and unblocking said inlet, a plurality o and independent Valves for controlling the the containers with said passage way.

4. Adevice of the character described including a nozzle having an air passage Way therethrough With a restricted discharge, an inlet to said passage Way, a means for blocking and unblocking said inlet, a 'plurality of containers communicating separately With said passage Way and being fixed relative to the nozzle, and independent valves for controlling separately the communication of the containers with said passage Way.

5, A device of the'character described including a nozzle having an air passage Way therethrough with a restricted discharge, a needle valve for restricting said discharge, an air inlet to said passage Way, a means for blocking and unblocking said inlet, a plur relative to the nozzle and communicating separately with said passage Way and independent valves controlling the communication of the containers, separately, With said passage way.

6. A device of the character described including a nozzle having an air passage way therethrough with a restricted discharge, a plurality of containers fixed in i position relative to the nozzle and communicating With said passage Way, a valve normally blocking the communication of each container With said passage Way, and means for admitting and excluding the passage of air through said passage Way.

In testimony whereof l have signed my name to this specication in the presence of two subscribing Witnesses.
